Abstract
The utility model relates to a fan blade angle adjusting device for a fan of a cooling tower, the key technical points thereof are as follows: a dial scale is fixed on a blade assembly, the blade assembly is fixed on a hub assembly by U-shaped bolts, and a pointer is fixed on the hub assembly by screws, thus forming the fan blade angle adjusting device for the fan. The fan blade angle adjusting device for the fan of the cooling tower adopts the structure formed by the dial scale and the pointer in a matching way, and overcomes the deficiency of lower accuracy of angle adjustment of the fan due to indirect and inaccurate alignment to scale marks in the past.
Description
One, technical field:
The utility model relates to the fan blade angle regulating device of blower fan of cooling tower.
Two, background technique:
At present, the general employing of the adjustment of blower fan of cooling tower blade angle directly done high scale on the blower fan axle, utilize the plane of certain other part or the angle that point is adjusted blower fan, because it is less to be confined to the diameter of blower fan axle, the scale precision is lower, moreover do not aim at graduation line directly and accurately, so the adjustment precision of blower fan angle is lower, have a strong impact on the service behaviour of blower fan.
Three, summary of the invention:
It is a kind of simple in structure that the purpose of this utility model will provide exactly, the fan blade angle regulating device of the blower fan of cooling tower that cost of production is low, and the utility model provides following technological scheme for this reason:
The fan blade angle regulating device of blower fan of cooling tower, comprise hub assembly, U-bolt, dial, pointer, screw, blade assembly, it is characterized in that dial is fixed on the blade assembly, the blade assembly is fixed on the hub assembly with U-bolt, and pointer is screwed the fan blade angle regulating device that constitutes blower fan on hub assembly.
Use the utility model can reach following beneficial effect: can accurately adjust the blade angle of blower fan, guarantee the service behaviour of blower fan.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross section structure schematic representation of the present utility model.
Among the figure, 1, hub assembly; 2, U-bolt; 3, dial; 4, pointer; 5, screw; 6, blade assembly.
Five, embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises hub assembly 1, U-bolt 2, dial 3, pointer 4, screw 5, blade assembly 6, dial 3 is fixed on the blade assembly 6, blade assembly 6 usefulness U-bolts 2 are fixed on the hub assembly 1, and pointer 4 usefulness screws 5 are fixed on the fan blade angle regulating device that constitutes blower fan on the hub assembly 1.
The method of adjusting the blower fan angle is: rotating pointer 4, make its outer rim of pressing close to dial 3, and angle value is on demand aimed at a certain corresponding graduation line of dial, tightens the nut of U-bolt, realizes the accurate adjustment of angle of fan leaves.
